Having a lot a trouble viewing any objects. Eclipse starts up, and can
create a BPMN project, but any BPMN elements in the pool (e.g the initial
task shape) disappear. I can only see them when I click on the down arrow
in the top left corner of the pool - sorry don't know what the icon is
called) and it disappears immediately afterwards.

So I'm stuggling to create *anything*, and I figure something's wrong with
my set up.
